Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Lift the rear of the vehicle using a jack and secure with jack stands.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Torque wrench
Brake cleaner
C-clamp or brake caliper tool

2. Remove Wheel

Use a lug wrench to loosen the lug nuts of the rear wheel.
Raise the vehicle with a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor. Do not disconnect the brake line.
Use a C-clamp to compress the caliper piston back into its housing.
Remove the old brake pads from the caliper bracket. Note their orientation for installation of new pads.
Clean the caliper bracket and apply brake cleaner to remove dust and debris.
Install new brake pads into the caliper bracket, ensuring they are properly aligned.

4. Inspect and Replace Rotor (if necessary)

Check the rotor for any scoring or wear. If damaged, proceed to replace.
Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install the new rotor, ensuring it is seated properly against the hub.
Tighten rotor screws to the manufacturer's specification.

5. Reassemble Brake Components

Slide the caliper back over the new pads and rotor.
Reinstall and tighten caliper bolts to the specified torque value (consult service manual for specific torque specs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle from jack stands and remove the jack.
Tighten lug nuts to the manufacturer's torque specification in a crisscross pattern.
Pump the brake pedal several times to seat the brake pads against the rotor before driving.
